Selection of Species to be Kept.
It would be erroneous to say that all species of salamanders can be successfully kept in captivity, because, as with other groups of animals, there are types which are hardy in captivity, and there are types which are extremely delicate. It is recommended that only the more hardy species be considered for keeping in the home.
As far as local species are concerned, the various mole salamanders (genus Ambystoma: the tiger, spotted, and small-mouthed salamanders) seem to do well in captivity. They may live a long time (up to 10 or 12 years for some). They are large (hence, will eat food that is more available), and they do not require a special temperature range.
The central newt, Notophthalmus v. louisianensis, which is locally common, or the red-spotted newt, N. v. viridescens, which is sold in pet stores, are rather hardy, if kept properly. The mudpuppy and hellbender may do well, but they require considerably more space, and should be given a few flat rocks to hide under.

The smaller salamanders of Missouri are on the whole delicate and require cool temperatures. The best one to try to keep for a while in captivity is the slimy salamander, Plethodon g. glutinosus. The rest of the smaller salamanders (genus Plethodon and Eurycea) are usually difficult to maintain. If you do secure some of these, it is recommended that they be kept a short time for observation, and then released in the same area where they were taken.
Remember: several species of Missouri salamanders are protected by the Missouri Conservation Department. If you plan to collect your own specimens, be sure to follow all laws of the Conservation Dept. No animal can be collected in a state or national park, or taken from any cave.
